The velocity of spherically-diverging detonation waves was measured in RX-26-AF, LX-17 and LX-10 explosives at 20°C and −54°C for detonation wave radii from 13 −50 mm. At the smaller radii the measured velocities were lower than published steady detonation velocities by as much as 4%. The detonation velocities measured at −54°C were usually higher than those measured at room temperature. These results indicate that a significant part of the excess transit time observed when an explosive is initiated by a point or hemispherical detonator may be due to a low detonation velocity. |
